HomeBackend DevelopmentPHP Tutorialjavascript - 跳转适配和代码适配分别用什么技术实现?

在移动端适配PC端网站技术上,官方提供了三种适配方案:响应式设计、动态提供内容(代码适配)和单独的网址(跳转适配)。但是身为前端的我只知道响应式设计,不知道另外两中的技术实现。

概念来自:
google、百度

我现在认为
跳转适配主要是使用JS判断用户使用的浏览器是移动端还是PC端。然后跳转到指定网页,例如baidu.com/index.html跳转到m.baidu.com/index.html
SEO的话提交给搜索引擎这两个网页的关系。

代码适配是获取HTTP请求头中浏览器的内容判,使用PHP(或其他后端语言)判断设备从而返回针对不同设备的内容,URL不改变。

不知道自己这样想对不对,求指正和补充,谢谢

如果要根据浏览器的UA来确定访问的是PC端还是Mobile端

在nginx中做重定向应该会比较好,这样对前端代码和后端服务器代码都没有侵入性。

这应该是题主说的跳转适配吧。

刚好我不知道第一种 响应式设计 怎么做的,但是知道后两种:

动态提供内容:后端代码可以检测当前请求的来源设备,网络情况,由此来决定如何渲染内容,渲染不同的模板或者不同的数据格式……

单独的网址:m.xxx.com 要么是单独的应用,比如手机版WAP的淘宝,或者H5.XXX.COM,这样的,或者是其实就是第二种的变种,只不过是路由不同而已,一般前者适应于大型的应用,如淘宝,后者则比较简单。

现在我也差不多知道了我不知道的第一种了,谢谢你。

但是我有一个疑问:“响应式设计”无形之中会增加一些成本吧,原本单一的网页,响应式设计后体积会变大吧?
